ASN.1 Language Support for Visual Studio Code

This extension provides IntelliSense-like editing and encoding/decoding (DER/BER/OER/COER/PER/UPER/JER) for Abstract Syntax Notation One (ASN.1). For example (*):

• Syntax highlighting and coloring.
• Auto-completion and Code Snippets.
• Formatting, Renaming, Go To Definition, Find All References.
• Schema and Value validation and error highlighting.
• Encoding, Decoding and Mockup Value Generation.

(*) Some features may be available commercially.

Usage

Open an existing ASN.1 schema file or create a new one (the file should have the .asn extension) and start editing.

Generate and Encode a Value

Snippets Autocomplete

Requirements

• .NET Core Runtime version 3.1
• Visual Studio Code (1.34 or higher)

Known Issues

The extension might not work properly in Ubuntu if you installed the .NET Core Runtime from a snap. Add /snap/dotnet-sdk/current to your PATH instead of creating an alias as suggested in the documentation.

If the extension issues a Launching server using command dotnet failed error, you might try installing the OmniSharp extesion and relaunching the editor.
